Drive Slow, Save Gas?

Did you know that your driving habits might be ruining your gas mileage? That heavy right foot of yours could be costing you money. Slow acceleration and strict adherence to speed limits can save gas. Why spend all that money on a fuel efficient vehicle only to blow it as soon as you're the one behind the wheel?

My Mazda Demio. 1.3 is using too much petrol

Okay- thanks for the public announcement;...just kidding!
Mike it sounds like you have a heavy foot on the gas pedal- speeding around town- Ohhh, I gotcha' again! Or someone is pilfering your gas by siphoning it out; LOL

Okay, all kidding aside, the following issues can cause poor fuel economy:
  1. Incorrect tire pressure
  2. a bad or malfunctioning oxygen sensor
  3. dirty or plugged air filter
  4. dirty or malfunctioning fuel injectors
  5. improperly working spark plug(s) e,g. misfires or improper gap
  6. poor driving habits, like sudden accelerations
  7. engine idling for inordinate or extensive amounts of time
  8. and as silly or unbelievable as it might sound, the type of motor oil...the viscosity that is used can affect gas mileage by up to 10-12%; regular oil changes using synthetic or manufacturer recommended oil that reduces friction should be employed.
  9. Defective coolant sensor
  10. Defective thermostat
  11. a leak in the intake manifold or EGR
  12. Poor compression- If you are driving a car that has high mileage, over 100,000 miles, affects fuel economy
  13. clogged catalytic converter or some other restriction in the exhaust system
  14. Dragging brakes
  15. slipping clutch or transmission
  16. Lugging around excess weight in the car
Any single one of...or combination of the above, could greatly reduce engine performance and affect gas mileage.

This is on a 2002 isuzu rodeo

To many things will cause fuel mileage to drop. First thing to do is read the codes(write them down). Erase them, them read them again. If it a code comes right back, check it first. No codes, drive it for 10 minutes or so, Check codes again. If they reappear check them . Some codes only come back after driving two times.

What is the typical mileage per tank? Does anyone know? How can I improve the miles

car is 24mpg, city.
so 15.6 MPG sucks it does. but is possible if you let my 15yo kid drive car, it is easy, to do, fast right and heavy foot, for sure.

is that averaging 3 tanks, as that prevents ISLAND pump shut off
issues. (varies)
did you check miles with GPS, to see if your speedo/odommeter is a bit nuts?

here are the basics, i can list 100 things, but here are a few.
  1. measured wrong. not 3 times avg. (use same gas station and pump) use GPS for true miles. (then switch stations and repeat)
  2. bad driving, (teenager? in house?)
  3. stolen fuel?
  4. brakes dragging.?
  5. running 15psi in tires,? (oh'bummer said it ,!)
  6. engine running bad, driving with the CEL lamp glowing? DTCs stored, scan the PCM> look see.? fix.
  7. never ever tuned it UP, this decade?
  8. Pulling a heavy load.?
  9. measured only on the up hill run in the rocky mountains, (i just did that)
  10. transmissions slips or TCC lockup failing. (scan the PCM)
  11. not coasting down hills( cuts fuel 100%) see #2
  12. old fuel?
  13. ill stop.

My car goes through $25 (CANADIAN) a day in gas.

Hi, I think you may have a leak in the tank. Walk around the car and smell around and under. Also check the fuel lines under the car.
Hope that helps

I would like to know how to get better gas mileage on a car-do I need a new air filter-it is only a 4 cylinder car.

The best way to improve gas mileage is to change your driving habits. K&N filters claim they can increase mileage, but there really is not 'miracle device' that can do so. Make sure the vehicle is running well, plugs and wires are all in good shape, air and fuel filters are clean.

Stay on highways as much as possible, and drive around with a glass of water that has no lid and is filled pretty high. Attempt to drive without spilling the water. This will drastically improve economy.

Have a 2008 sedona, since i bought it when i turn on the engine i get a heavy fuel smeil. The dealer said its normal. As well it burns fuel like mad, nothing like it reported by EPA.

if you can smell fuel then something is wrong. if you smell it only out of the tailpipe then if there was a problem the check engine light would be lit up. raw fuel could be leaking at a fuel line or component and unless is severe would not cause a engine didnt state what your mileage is your getting but alot of things cause poor mileage number one is driving conditions and can increase gas mileage more than 15 miles to the gallon on alot of cars just by paying attention to driving habits. also it is important to clean the throttle body regularly. a dirty one causes all kinds of problems and low fuel mileage is one of needs to be physically cleaned,no in tank treatment or additives will do the job.if you take to a shop make sure you see a tech taking of air intake tube and cleaning it with some sray AND a brush. some shops just put additives in the gas and oil and sometimes in a vacuum hose or throug the fuel is an inexspensive service [when not included in a fuel injection cleaning package] and should be done at 30,000 miles or sooner depending on drive conditions etc.
